摘要
使用Aspen Plus对反应精馏隔壁塔(RDWC)合成氯乙酸甲酯(MCA)工艺进行模拟,在单因素分析的基础上,采用响应曲面法,建立了二次回归模型,分析进料位置、进料量、回流比、气相分配比等因素对能耗的影响,从而确定了最优操作参数。当甲醇进料位置N为21、氯乙酸进料量F1为41.28kmol/h、RD-1塔回流比R1为0.42、FS气相分配比X为0.83、RD-2塔回流比R2为0.39时,产品纯度可达到99.93%,总负荷Q为2536.152kW。
The reactive dividing wall column(RDWC)process for synthesizing methyl chloroacetate(MCA)was simulated by Aspen plus.On the basis of single factor analysis,a multi-factor analysis method—response surface method(RSM)was used to establish a quadratic regression model to analyze the influence of feed location,feed flow,reflux ratio and gas distribution ratio on energy consumption,so as to determine the optimal operating parameters.Under the optimized operating conditions:methanol feed position N of 21,chloroacetic acid feed flow F1 of 41.28kmol/h,RD-1 column reflux ratio R1 of 0.42,FS gas distribution ratio X of 0.83 and RD-2 column reflux ratio R2 of 0.39,MCA product purity can reach 99.93%,and the total energy consumption Q is 2536.152 kW.
